It is our thought that your Public Health Bulletin No. 163, 1926-Series 3, amended June 28, 1946, -which covers the regulations for properly advertising fuel containing leaded gasoline on filling station dispensing pumps also oovers the labeling of stationary and mobile refuelers handling aviation leaded gasoline at airport installations. Before advising all concerned in our operations of this fact we would like you to verify this thinking and also to advise any specifications you may have for installing the signs on mobile equipment and on fVieling pits flush with the runway ramp. It is our thought that your regulations for installing the lead signs cn stationary dispensing equipment that is similar to a service station pump is adequately covered by your present regulations. Your earliest advioe on this problem will enable us to properly handle what we feel is a necessary precaution against a recognized hazard at our airport installations. Yours very truly N M. F.
